Mark Hamill has promised to share details about “Star Wars: Episode 8” that will apparently “blow your mind.” Meanwhile, new pictures from the production set at Ceann Sibeal in Co Kerry leak online, giving a closer look at the new Ahch-To planet.

Hamill (Luke Skywalker) asked the fans to prepare themselves, as he is going to make a big revelation on Daisy Ridley’s (Rey) birthday. The revelation will be made on Sunday at 8 p.m. and it is “guaranteed to blow your mind.” The actor added that this was not a joke, trick or a prank.

Previously, Hamill had made a few fans angry when he said that he would reveal some exclusive details about the plot of the movie. It turned out to be an April’s Fools Day prank and the actor acknowledged that not everyone was happy about it.

Several fans told Hamill that they are finding it difficult to believe him. Some of the fans believe that it is another prank, but others want to believe that the actor will really reveal something about “Star Wars: Episode 8” this time.

The actor teased that the revelation is going to be a behind the scenes picture that will “rock,” “hard.” Since the actor is choosing Ridley’s birthday to share the picture, it is expected to be something that shows Luke Skywalker and Rey together.

The two characters were last seen on the planet Ahch-To. The new planet was introduced in the movie “Star Wars: The Force Awakens.” The planet has been a home to Luke for a long time.

Pictures from the set posted on Irish Examiner show the set at Co Kerry resembling the set at Skellig Michael. Filming for “Star Wars: Episode 8” at this location will reportedly begin next month and will last two weeks.
